The following figure shows a core topology with two access rings. In this topology, there are two EAPS common links.
In the right-angle topology, there are still two EAPS common links, but the common links are adjacent to each other.
To configure a right-angle topology, there must be two common links configured on one of the switches. The following figure shows a right-angle topology.
The following figure shows a combination basic core and right-angle topology.
The following figure shows an extension of the basic core and right angle configuration.
The following figure shows a single large core ring with multiple access rings hanging off of it.
This is an extension of a basic core configuration.
